Fabric

Entering April and May, with abundant sunshine and significantly warming weather, although it is not yet summer, products such as sunscreen clothing, hats, and face masks have already begun to roll up

Sunscreen needs

The basic demand of consumers for sunscreen clothing has shifted from a single sunscreen function to a pursuit of comprehensive protection. Modern consumers not only need effective UV protection during outdoor activities, but also hope that sun protection clothing has good breathability, moisture absorption and sweat wicking ability, and comfort. This means that sunscreen clothing should not only be able to block ultraviolet rays, but also ensure a comfortable experience for the wearer in hot weather; Choosing a suitable sunscreen suit should focus on the functional aspects of fabric selection

Standard for sunscreen clothing fabrics

UPF

UPF (Ultraviolet Protection Factor) is an important indicator for measuring the sun protection effect of sunscreen clothing. The sunscreen fabric needs to meet this standard to ensure that the wearer can receive effective UV protection during outdoor activities

Ultraviolet rejected

UV blocking rate is another key indicator that measures the ability of sunscreen fabrics to block the two main harmful UV rays, UVA and UVB

Coolness coefficient

In the hot summer, the comfort of the wearer is equally important. The coolness coefficient is an indicator that measures the coolness that sunscreen clothing brings when it comes into contact with the skin. The cooling coefficient of knitted fabrics needs to reach ≥ 0.2qmax [J/(cm) ²• s) ], woven fabric ≥ 0.18qmax [J/(cm) ²• s) This cooling coefficient ensures that sunscreen clothing not only provides sun protection, but also has good heat dissipation performance, keeping the wearer cool and comfortable

Gram weight

Weight refers to the weight of the fabric, which directly affects the portability and wearing comfort of sunscreen clothing. There are clear requirements for the unit weight of both knitted and woven fabrics, with knitted fabrics ≤ 190g/㎡ and woven fabrics ≤ 75g/㎡. This weight control makes sun protection clothing both lightweight and easy to carry, suitable for various outdoor activities and daily wear

Washability

The washability of sunscreen clothing refers to the ability of a product to maintain its sun protection performance even after multiple washes
After 30 washes, the sunscreen fabric should still maintain a UPF50+sunscreen effect. Even under frequent washing, it can maintain efficient sun protection ability
